2006 Buick Rainier Keyless Entry Remote Fob Programming Instructions

Important Notice: The 2006 Buick Rainier supports onboard programming for keyless entry remote fobs. Follow the steps below to program new or additional transmitters.

Programming Instructions:

  • Step 1: Ensure all doors are closed completely before starting the process.
  • Step 2: Insert the key into the ignition, but do not turn it yet.
  • Step 3: Press and hold the power UNLOCK button on the driver’s door panel. Continue holding this button until instructed to release in a later step.
  • Step 4: Perform the following four steps in quick succession:
  • Step 5: Turn the ignition to the ON position (just before engine start).
  • Step 6: Turn the ignition back to the OFF position.
  • Step 7: Turn the ignition to the ON position again.
  • Step 8: Turn the ignition back to the OFF position.
  • Step 9: Release the power UNLOCK button. The vehicle will automatically lock and unlock the doors to confirm it has entered programming mode.
  • Step 10: On the remote you wish to program, press and hold the LOCK and UNLOCK buttons simultaneously. Hold both buttons until the vehicle cycles the door locks again. This may take up to 30 seconds.
  • Step 11: Repeat Step 10 for each additional remote, including any existing ones, as only remotes programmed during this session will remain functional.
  • Step 12: Turn the ignition to the ON position to exit programming mode. Programming is now complete.

Additional Tips: Up to four remotes can be programmed during the same session. If the vehicle does not respond during Step 9 or Step 10, restart the process from the beginning. After exiting programming mode, test each remote to verify proper operation of all functions.
